Abstract

The invention discloses a real-time detecting system for the vibration screen treatment amount. An acceleration sensor is used for detecting acceleration signals in the middle of a screen body in the vertical direction in real time, force sensors are used for detecting force signals of a vibration screen in the vertical direction in real time, and a signal collecting card collects the acceleration signals and the force signals in real time and uploads the acceleration signals and the force signals to a computer for treatment. The invention further discloses a real-time detecting method for the vibration screen treatment amount. The method comprises the steps that firstly, acceleration time domain signals and force time domain signals are detected in real time; secondly, the time domain analysis is carried out on the acceleration time domain signals and the force time domain signals, and corresponding amplitudes are obtained; thirdly, the Fourier transform is carried out on the acceleration time domain signals, and work frequency is obtained; fourthly, a stress model of the vibration screen in the working process is analyzed; and fifthly, the real-time treatment amount of the vibration screen is worked out. The treatment amount of the vibration screen can be accurately detected in real time, and the real-time detecting system and method have the advantages of being high in automation degree, economical efficiency and precision and can be used for guiding the technology parameter optimization or adjustment of a coal preparation plant production line.
